An exceptional pair of earrings from Margot van Voorhies Carr, whose shop was called Margot de Taxco. Circa 1950sThey are like a piece shown on the back cover of Penny C. Morrill's book "Margot van Voorhies, The Art of Mexican Enamelwork".Certainly one of the most sought after designs that Margot produced, her serpent, or snake, is very rarely seen. Copies abound, but these earrings are original and authentic Margot pieces. The confetti green enamel is actually a myriad of colors, with various shades of greens, browns, blues, and yellows. All translucent. The collar and eyes are a gorgeous turquoise blue .The snake head is 1 3/8" X 13/16", with a depth of 3/8'.Weighs approx 15 grams.Hallmarked "5554", with the eagle assay 16. 5554 is the number for Margot's snake/serpent design. No other marks that I see, but it's definitely an authentic Margot de Taxco piece, and likely was part of a parure. It was not uncommon for some pieces (especially smaller ones), to not have all hallmarks on them.In very good vintage condition. If you would like additional photos, just message me.Margot van Voorhies Carr, professionally known as Margot de Taxco, first came to Mexican in 1937. Married to Don Antonio Castillo, she created many of the early designs for Los Castillo. Her own shop, "Margot de Taxco", opened in 1949 after her divorce, and included over twenty silversmiths and ten enamelists, with Sigi Pineda overseeing the enamelers for four years before opening his own shop in the mid-1950's.
